Dungeons & Dragons: Adventures in the Forgotten Realms

Asmodeus the Archfiend | Legendary Creature | Devil God | Binding Contract — If you would draw a card, exile the top card of your library face down instead. {B}{B}{B}: Draw seven cards. {B}: Return all cards exiled with Asmodeus the Archfiend to their owner's hand and you lose that much life. | Aleksi Briclot

Baleful Beholder | Creature | Beholder | When Baleful Beholder enters the battlefield, choose one — • Antimagic Cone — Each opponent sacrifices an enchantment. • Fear Ray — Creatures you control gain menace until end of turn. (A creature with menace can't be blocked except by two or more creatures.) | Lars Grant-West

Xanathar, Guild Kingpin | Legendary Creature | Beholder | At the beginning of your upkeep, choose target opponent. Until end of turn, that player can't cast spells, you may look at the top card of their library any time, you may play the top card of their library, and you may spend mana as though it were mana of any color to cast spells this way. | Kieran Yanner
